A method is disclosed for providing a tuned mass damper for a powertrain component. The method includes the steps of providing a mount adapted to be attached to the powertrain component; assembling a mass element to the mount; and molding an elastomeric body around the mass element to bond the mass element to the mount. The tuned mass damper assembly for a drivetrain component is also disclosed that may be attached to a mount having an opening that extends through the mount or a housing portion provided on the mount The molded elastomeric body integrally attaches the mass element to the mount. Alternatively, the tuned mass assembly may be bonded to a plate that is attached to a motor retention element.

A powertrain torque roll restrictor includes a first bracket having an elongated body defining a first bracket opening at a distal end and a central axis, a second bracket coaxial with and adjacent to the first bracket, and a third bracket coaxial with and adjacent to the second bracket opposite from the first bracket, with the third bracket defining a third bracket opening cooperable with the first bracket opening. The second bracket defines a second bracket opening receiving the elongated body such that the second bracket is positioned about the elongated body. The powertrain torque roll restrictor further includes a first rubber element positioned between the first bracket and the second bracket, and a second rubber element positioned between the second bracket and the third bracket, with the brackets being configured to hold the respective rubber element in compression.
